PowerShell attach removes existing breakpoints in attached session

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.

Summary

I use VSCode PowerShell debugger by attaching to a process hosting PowerShell.
Attaching removes breakpoints that I have already set in my session.

Extension Version

ms-vscode.powershell@2023.3.3

Steps to Reproduce

(1) Invoke the below script test1.ps1 in some PowerShell session. E.g. I used and saw the problem in powershell and pwsh consoles and in my application hosting PowerShell as well.

function global:test1 {
	'hi'
}
Set-PSBreakpoint -Command test1
Set-PSBreakpoint -Script $PSScriptRoot\test1.ps1 -Line 2

(2) Run Get-PSBreakpoint -- see 2 breakpoints

(3) In VSCode, launch/attach PowerShell debugger configured as below.
Select the target process where we have set 2 breakpoints.

      {
        "type": "PowerShell",
        "request": "attach",
        "name": "PowerShell attach",
        "processId": "${command:PickPSHostProcess}",
        "runspaceId": 1
      },

(4) With the debugger attached, run Get-PSBreakpoint again -- see that breakpoints are gone.

Reproduce el problema con el script proporcionado test1.ps1, dos llamadas a Set-PSBreakpoint y la configuración de attach de PowerShell mediante PickPSHostProcess. Empieza rastreando el flujo de attach del depurador y compara Get-PSBreakpoint antes y después del attach. Se considera terminado cuando el attach conserva ambos breakpoints existentes; en el issue no se indica ningún archivo de prueba ni ningún punto de entrada del código fuente.
